Am I hurting my car without a reflash?

I just need to know one thing, Is my engine at risk for running too lean?
This is what I've done: MRT 3'" turbo back w/cat, BPM up pipe, Hacked air box w/K&N, I/C hoses.
The car runs great, lots of low down power, no hesitation, but mild boost spike (16.5) then returns to normal .
A reflash is comming next spring, but untill then?

YOu should be fine, there are a lot of poeple running exhaust and no tunning. Just keep an eye on the boost and make sure it doesnt go above 16.5psi. Once you get the tunning you will gain better drivability and horse power.
